Referring to the drawings, reference number 5 deno sas a whohn anautomobile door having its stiles 6 'g'irovided with guides 7 for asliding glass 8. 1 The lower edge of the glass has a binder strip 9secured thereto, and at tachcd to this strip is a bracket 10, thepurpose of which will be described hereinafter. Butlers 11 serve tolimit the downward movement of the glass.

At that side of the door opposite the lock 12, a bracket 14 is securedto the inner face of the adjacent stile, and on this bracket is mountedthe window regulating); mechanism. The bracket ll comprises a flatattaching portion having a pair of screw slots 16 through which pass thesecuring screws, and a circular clamping and post attaching portion 17.This latter portion is provided with a circular beveled ed 5 drecess'18, in the center of which is carried a post 19 which may befixed to the bracket by providing a should or to engage the sidethereof, and by riveting over the end as illustrated by Fig. V. Aeounterbalanco lever 2-2 is pivotally inounteiil :it one end on the post19, and at tits free end, carries a roller 23 having a concave face tofit the rounded edge of the strip 9. The aforementioned bracket 10 has aflange 241 along its lower edge, which is en; gm bv the roller 23 whenthe window is lower ed.

eouuterbalanon sg iring 26 "is adjustably conis cut away as at 29, andthe opening thus made, covered by a plate 30.

A handle 32, by which the window is shifted, has a flange 33 whichoverhangs and slides on the inner-covering 34 of the door and ispivotally mounted upon the post 19. On its under side, it is providedwith a channel to receive the end of the counterbalance lever. A disk 35having; its edge beveled to correspond with the bevel of the recess inthe bracket 141 is secured to the counterbalance lever 22 by two screws36, and is also secured to the handle 32 by two other screws 37positioned at right angles to the first mentioned screws. by heldtogether as a unit, freely rotatable on the post 19, and also free tomove axially thereoz'i. For clan'iping the lever and handle in anydesired position of adjustment, a winged nut 38 is threaded on the outerend of the post 19 so that when the same is turned in one direction, thedisk 35 is pressed into wodgiug engagement with the bracket 14.

'llhe adjoining poi. ions of the handle and the nut are shown providedwithenlargedbores which receive a coil. spring 40, the purpose of whichis torcsiliently hold the disk and bracket in engagement when the nut isloosened, and to prevent rattling of the parts. A screw 41 threaded intothe end of the post 1.9 and having its head seatedin a counter sink inthe nut 38, limits the outward movement of the nut.

To change the adjustment of the window having the above describedadjusting or reglu lat-.ingmechanism, it is only necessary to loosen thewinged nut 38, move the handle 82 the desired amount in the properdirection, and t ten the nut. The window being counterbalanced. littleeffort is required in 'moving' the handle, and the angle moved issomewhat less than a right angle with the parts constructed and arrangedas illustrated.

It will be noted that the above described construction is extremelysimple and sturdy, comprises but a low parts, is easily operated, andmay be clamped to hold the window precisely in any des red position.

Havin thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

The handle, lever and disk are there- 1. A window-lift support for avertically slidable window, comprising a lift arlnfor actuating awindow, a bracket having a conical recess mounted adjacentsaid window, apivot post fixedly mounted within said recess, a conical member securedto said window liftarm, said conical member being rotatable on said postandadapted i0 fit Within said recess, clamping means on said'post forforcing said conical member into engagement wit-lithe conical walls ofsaid-recess, and a spring for-lightly urging saidconical memberinto-said recess when'the clamp is 100senedr Y v 2.

In testimony whereof, I aflix my signature.
